Abstract
The molecular structures of the lowest-energy conformers of donepezil (C24H29NO3), rivastigmine (C14H22N2O2), and galantamine (C17H21NO3), which are extensively used in Alzheimer's disease and other memory disorders, were identified using the Spartan06 program and the MMFF method. The optimized geometries, obtained with the same method, were used as initial data in molecular docking investigations with the Acetylcholinesterase enzyme. The binding modes, binding affinities, and interactions were comparatively determined as consequence of the calculations.
